Everything that humans hear is in the fo...

    Everything that humans hear is in the form of waves(). Just as the eye sees light waves in the form of colors, the ear hears sound waves in the form of noises. The ear and the eye turn these different waves into signals that the brain(大脑) can make sense of.

The ears and brain have an amazing ability to recognize(识别) particular sounds. For example, a mother often can tell when her baby is crying even if there are other crying babies in the same room. This is because the sound of her baby’s cry has special meaning to her and the brain has recorded its importance.

The ability to recognize sounds improves with experiences. As the brain receives information about sounds from day to day, it stores the information in its memory. When the brain hears new sounds, it gives meaning to them based on the information already in the memory. This is why certain words or songs can make a person happy. Often it is not the words or songs themselves that cause this feeling. The sounds are connected to happy memories for that person.

Another hearing process controlled by the brain is to decide where a sound is coming from. One ear is usually closer to the source(来源) of a sound than the other ear is. Sound waves are stronger when they reach the ear that is closer. They also reach the closer ear first. The brain recognizes these differences and uses them to decide the location of the source of the sound.

1.Which of the following shows the normal hearing process of a mother hearing her baby crying?

a. The ears receive the sound waves.

b. The mother recognizes her baby’s cry.

c. The baby’s turn the sound waves into signals.

d. The baby’s cry travels in the form of sound waves.

    If you are driving out of Montpellier, a city in France, please look out for the signboard(路标) with the words “Millau Viaduct(米洛高架桥)”. Turn towards it and get ready to take the drive of a lifetime.

The Millau Viaduct is the world’s tallest bridge. It is 343 meters high and about 2.5 kilometers long. The bridge is between Paris and Montpellier, and it was built in 2004 at the cost of $530 million. And why was it built?

For years, the French government thought over the problem of traffic congestion for people travelling from Paris to the south of France. Many ideas were suggested, but one idea was finally accepted. Instead of choosing to build a highway that went through the hilly(多) south of France, they decided to build a bridge over the Tarn River. This bridge would not just be like any other bridge. It would start at the top of one hill and connect to another hill on the other side of the river. This bridge would shorten            the highway by 60 kilometers. It would save people’s time and money. _____________________

Engineers had to find out a way to build the bridge quickly, over 300 meters up in the air and about 2.52kilometers long across the river. It was very hard, but finally engineers succeeded in finding a quickest way to build it. It is very convenient for people to travel and it has been consistently(一致地)ranked as one of the great engineering achievements of all time.

    So you thought the hamburger was the world’s most popular fast food? After all, McDonald’s Golden Arches span the globe. But no, there is another truly universal fast food, the ultimate fast food. It’s easy to make, easy to serve, much more varied than the hamburger, can be eaten with the hands, and it’s delivered to your front door or served in fancy restaurants. It’s been one of America’s favorite foods for over 50 years. It is, of course, the pizza.

It’s kind of silly to talk about the moment when pizza was “invented”. It changed over the years, but one thing’s for certain—it’s been around for a very long time. The idea of using pieces of flat, round bread as plates came from the Greeks. They called them ‘plakuntos’ and ate them with various simple toppings such as oil, garlic, onions, and herbs. The Romans enjoyed eating something similar and called it ‘picea’. By about 1000 AD in the city of Naples, ‘picea’ had become ‘pizza’ and people were experimenting with more toppings: cheese, ham, anchovies, and finally the tomato, brought to Italy from Mexico and Peru in the sixteenth century. Naples became the pizza capital of the world. In 1889, King Umberto and Queen Margherita heard about pizza and asked to try it. They invited pizza maker, Raffele Esposito, to make it for them. He decided to make the pizza like the Italian flag, so he used red tomatoes, white mozzarella cheese, and green basil leaves. The Queen loved it and the new pizza was named ‘Pizza Margherita’ in her honour.

Pizza migrated to America with the Italians at the end of the nineteenth century. The first pizzeria in the United States was opened in 1905 at 53 Spring Street, New York City, by Gennaro Lombardi. But the popularity of pizza really exploded when American soldiers returned from Italy after World War and raved about ‘that great Italian dish’. Americans are now the greatest producers and consumers of pizza in the world.

1.Which is the correct order of the change of pizza?

A.Plakuntos→pizza→picea B.Pizza→plakuntos→picea

C.Picea→Plakuntos→pizza D.Plakuntos →picea→pizza

2.Why are Mexico and Peru important in the development of pizza?

A.Because pizza first became popular in these countries.

B.Because pizza was invented in these countries.

C.Because one topping was brought to Italy from these countries.

D.Because the people in these countries are the greatest consumers of pizza.

3.What do the Italian flag and a Pizza Margherita have in common?

A.There is a picture of a Pizza Margherita on the flag.

B.They have the same colours.

C.Both of them represent Italy.

D.They are both popular in Italy.

4.When did pizza become really popular in the United States?

A.After 1945. B.In 1889. C.In 1905. D.By1000AD

5.What is the best title for the passage?

A.McDonald’s and Pizza. B.Global Pizza.

C.Pizza in the United States. D.How to Make Pizza.
